FINGER-RING.

SPECIFICATION forming part of Letters Patent N 0. 665,089. dated January 1, 1901.

Application filed July 3, 1900. Serial No. 22,393. (No model.)

To all whom it may concern.-

Be it known that I, DAVID GREENBERG, a citizen of the United States, residing at New York city, borough of Bronx, county and State of New York, have invented certain new and useful Improvements in Finger -Rings, of which the following is such a full, clear, and exact description as will enable anyoneskilled in the art to which it appertains to make and use the same, reference being bad to the accompanyiugdrawings, forming part of this specification.

My invention relates to improvements in finger-rings; and the principal objects of the invention are to provide a ring in which light is admitted underneath the gems, so asto increase the luster of the same, and to lighten the weight of the ring and at the same time to cheapen the manufacture of the same.

To these ends myinvention consists in the various novel and peculiar combinations of the several parts of the article, all as hereinafter fully described and then pointed out in the claims.

I have illustrated a type of my invention in the accompanying drawings, wherein Figure l is a side View of my improved ring, showing a setting of three gems. The dotted lines in this view indicate the light-admitting chamber, which extends through the head of the ring, and the peripheral groove, which extends around the lower part of the ring. Fig. 2 is a plan view of the top or head of the ring. Fig.3 is a top view of two separated halves or blanks of which the ring is composed. Fig. 4: is an inner side view of one of the halves or blanks. Fig. 5 is a perspective view of the ring with the gems omitted.

Referring to the drawings, in which like characters of reference indicate like parts throughout, 2 designates the ring, having an enlarged upper part or head 3, which constitutes the mounting or setting for the gems 4.. In cross-section the ring diminishes or tapers uniformly upon each side, beginning at the center point 5 of the head, so that the plan view, Fig. 2, of the head shows each'sidethereof as convex or bowed outwardly. .The head of the ring is also arched from side to side, as shown in Fig. 5, so that it presents wellrounded edges. The gems 4 are set in suitable openings 6, formed in the top of the head,

and the head is formed with a chamber or channel 7, which extends through the head from side to side, so as to open upon the periphery of the ring at each side of the head. This chamber presents an unobstructed channel through the head, so that the light may enter each end thereof and be cast underneath the gems, which when translucent have their luster or brilliancy increased. In the bottom of the light-chamber 7 are formed suitable perforations 8, directly beneath the gems, and these perforations open upon the interior of the ring.

In making the ring I form thereon a peripheral groove 9, which leads from one end of the light-chamberaround to the other and gradually tapers or diminishes in width according to the taper of the ring, as shown in Fig. 5. This groove adds to the neat appearance of the ring and tends to conceal somewhat from the eye the lateral openings of the light-chamber. The presence of this chamber 7, which extends longitudinally through the head, in addition to admitting the light beneath the jewels serves also to materially lighten the weight of the article. In some instances in this general type of ring, which is known as the gipsy ring, I find that the presence of the chamber makes the ring some two pennyweight lighter than if the head of the ring were not chambered.

This peculiar construction of ring may of course be made from one piece of metal; but to do so proves both difiicult and expensive. For example, to form a smooth-walledchamher like the chamber 7 through the head of the ring requires a great deal of labor, and, in fact, it is practically impossible to do so. I therefore make the ring of two pieces 10 and 11, which are united by suitable solder or otherwise on the central plane extending at right angles to the axis of the ring, such plane being indicated at a b in Fig. 2. The two halves 10and l1 composing the ringare formed alike from suitable dies or molds, or otherwise, each being recessed in such way that when united such recesses together make up the chamber 7 in the head of the ring, likewise the peripheral groove 9, extending partially around the ring.

In using my invention I find that where other translucent gems the luster ofthe gem is considerably increased by virtue of the presence of the subchamber, which admits the light beneath the gems.

I wish to be understood as not limiting my invention to the exact construction herein set forth, as various modifications may be made in the same Without, however, departing from the spirit of the invention.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

1. A finger-ring having a suitablyshaped upper part constituting a setting for gems, the said part being provided upon its upper face with one or more openings in which the gems are set, a light-admitting chamber eX- tending through the material of said upper part of the ring and opening at each end thereof upon the periphery of the ring to ad mit the exterior light therein, the said chamber being in free communication with the said gemopenings, substantially as and for the purpose set forth.

2. A finger-ring having the upper part 3 constituting a gem-setting, such part being provided upon its upper face with suitable openings 6 in which the gems are set, a lightadmitting chamber 7 extending through the material of the upper part of the ring and opening at each end upon the periphery for admitting the exterior light Within the chamber, the said chamber and the gem-openings being in free communication, substantially as and for the purpose set forth.

3. A finger-ring having a suitably-shaped upper part constituting a gem-setting, said part being provided upon its upper face with one or more openings for the gems, a lightadmitting chamber extending through the interior of said upper part and opening at each end upon the periphery of the ring, the said finger-ring being formed from two similar halves, each recessed alike, and united upon a plane normal to the axis of the ring, the re cesses of said respective halves together com stituting the gem-openings and the light-admitting chamber with its periphe al openings, substantially as and for the purpose set forth. In testimony whereof I have hereunto set my hand in the presence of the two subscribing Witnesses.
